I got my first indoor cat palm about 3 months ago. At first it seemed to be doing ok, but it started rapidly browning at the tips, and then entire leaves would yellow. There was another very helpful post on here where someone explained about spider mites, overwatering, and other factors! Since then, I did determine it had spider mites and have been checking regularly to make sure they do not return and treated it with need oil. I also rinsed it off in the shower before hand to shake it out. I also cut off dying leaves at the trunk as instructed.
I water it once a week, and lately I’ve been waiting until it gets dryer than that. It doesn’t get too much sunlight, so I’m thinking that could be part of it. I’ve also seen posts that say the soil and the water hardness could be a problem. I live in DC and Google says our water is “moderately hard” and I had used Miracle Gro Indoor Potting Mix. I thought it was improving because it’s been growing new stems, but I’m seeing that they are showing early signs of browning at the tip. Does anybody have any advice? I’ve included one photo where it usually is in the apartment, and other by the window for better light.
